Application filed November 7, 18115. Serial No. 286,241.

To all whom it may concern:

Be it known that I, DANIEL BLAoKs'roNE, a citizen of the United States of America, residin at Shelb ville, in the county of Shelby and tate of Il inois, have invented new and useful Improvements in Elevators, of which the following is a specification.

This invention relates to elevators, and particularly to elevators of that kind employed,

for raisin grain and other materials from the roun to an elevated storage-place.

T e object of the invention is to provide an elevatin apparatus which may be operated by the ra t-aiiimals of vehicles conveyin the grain or other material to be elevate thereto.

Another obect of the invention is to provide a portable apparatus of this character which is adapted to be readily transported from place to place.

With these and other objects in view the invention consists of the novel construction and combination of arts hereinafter fully described and claime reference bein had to the accompanying drawings in whic Figure 1 is a view in side elevation, with parts in vertical longitudinal section, of an elevating and power apparatus embodying my invention. Fig. 2 is a to plan view, on an enlarged scaie, of the inc ined approach and supportin platform, the conve er, and the elevator, tle latter appearing in orizontal section. Fig. 3 is a rear end elevation of the apparatus, parti broken away to show the outiet-chute of tfie elevator and indicating in dotted lines a vehicle arranged in discharge position upon the approach and supporting platform and the conveyor folded in the position it occupies when out of use. Fig. 4 is a vertical transverse section through the lower end of the elevator and conveyor with the latter arranged in operative position. Fig. 5 is a detail side elevation of a portion of the tread-mill mechanism and showing the brake device.

Referring now more particularly to the drawings, the numeral 1 represents a vertically-disposed elevator frame or casing provided at its u per end with an outlet-chute 2. J ournaled in earin s at the to and bottom of this frame are Liafts 3 an f1, carrying sprocket-Wheels 5 and 6, supporting an endless elevator, comprising a chain 7, carrying buckets 8, which may be of any suitable form. At the lower end of the frame is a receiving-trough 9, opening through the front wall of the frame, and into which the material to be elevated is discharged from the Wagons or other vehicles. The buckets 8 when passing around the s rocket-wheel 6 take up this material an upon passing around the sprocket-wheel 5 discharge it into the chute 2, from which it may pass into a warehouse or other suitable storage-recon tacle. The shaft 3 extends at one end beyond the frame and carries a sprocket-wheel 10, while the shaft 4 extends at both ends beyond the frame and is provided at one end with a sprocket-wheel 11, which is connected by a chain 12 with the sprocket-wheel 1() to communicate motion from the shaft 4 to the shaft 3.

On the other end of the shaft 4 is a sprocketwheel 13 and a beveled pinion 14. The sprocket-wheel 13 is connected by a chain 15 with 'a sprocket-wheel 16 on one end of a shaft 17, journaled in bracket-arms 18, extending frorn Vthe front of the elevator-casing on opposite sides of the inlet. Pivotally mounted on this shaft 17 s a chute or conveyer trame or casing 19, carrying at its outer end a shaft 20, and around the two shafts 17 and 20 extends an endless belt 21, which is operated in practice by the gearin just described to convey the material to t e receiving-trougli 9. The conveyor-frame 19 is adapted to be lowered or swung down to a substantially horizontal position on the shaft 17 as a pivot, as shown in Fi s. 3 and 4, and is provided at its outer or resend with a hin ed leg 22 to support itin a horizontal or slig tl '-inclined position. The said frame 19 is a so adapted to be tilted up on the shaft 17 to a vertical position alongside the elevator-frame, as shown in Fig. 3, and is provided at its free end with a hook 23 to engage an e e 24 on the eievator-franie, whereby it may be fastened in an elevated position.

If desired, the frame of the elevator may be mounted on sills or Wheels, so that it may be readily trans orted from lace to place for use. A tiea -mill is emp oyed for communicating power to the elevator and conveyer and comprises a suitable supportin frame 25, which may be mounted ufpon si or runners 26 or e uivalent supports or read transportation. his frame carries an en less belt or treadlatforin 27, made up of a belt or chain suita ly connected and provided with cross cleats or projections 28 to afford a firm engagin surface for the feet of the draftanimals. The tread-belt 27 is mounted upon IIO 'a pivot brake-lever 44.

belt 38, as shown s rocket-wheels 29, carried bT transverse shafts 3() and 31, arranged at the front and rear ends of the frame 25, which latter is open at each end for the entrance and passage of the draft-animals.

Fig 1 of the drawings shows the a paratus in operative position with incline platforms 32 and 33 leading, respectively, to and from the entrance and exit ends of the treadmill. In practice these platforms will be provided with suitable footholds 35 for the draft-animals and the treadmill will be so arranged that the platform-approach 32 will lead upwardly from the inlet side of the elevator-frame 1, as shown in Fig. 2, so that the conveyer-frame 19 ma r be turned down at the lower or rear end o said platform 32 to receive the grain or other material discharging from a vehicle thereon, as shown in he shaft 30 of the treadmill apparatus carries at one end a sprocket-wheel 36, from which leads a drive-chain 37, which passes "around a sprocket-wheel 38 on an elevator drive-shaft 39, on which is also a beveled gear-wheel 40, which meshes with the pinion 14, so that when the tread-belt 24 is operated by the draft animals in the manner well understood motion will be communicated to the conveyer and elevator belts. If desired, suitable fastenings may be employed to hold the platforms 32 and 33 in fixed relation to the treadmill-frame 25-such, for instance, as hooks and eyes 41, shown in Fig. 1 as connecting one side of the platform 32 to the frame 25. The other end of the shaft 30 has fixed thereto a friction wheel or disk 42, adapted to be engaged by a brake-shoe 43 on The lever 44 extends upwardly between the adjacent side frame 25 and a guide and rack plate 45 and is guided in its movements thereby. The rack-plate 45 is formed on its inner end with rack teeth or notches adapted to be engaged by a fixed pawl or projection 46 on the lever 44, wherey the latter may be locked in applied and released positions.

In operation it will be understood that the conveyer-frame 19 is normally swung u to the position shown in dotted lines in Fig. 3 when the apparatus is out of operation. A wa on or other vehicle carrying material to be loisted is driven up on the platform 32 until the draft-animals pass upon the treadmillin Iig. 1, and the lower end of the wagon is arranged above the lower end of said platform, at which time the brakes of the wa on are applied or the wagon is checked to hoh? it in such position, and the brake-lever 44, which has previously been set to hold the treadmill-belt 28 from operation, is released, the chute or conveyer-frame 19 lowered for operation, and the end-gate of the wagon removed to allow the load to discharge by gravity thereon. The operation is so timed that the instant the draft-animals pass fully onto the tread-belt 28 the parts are adjusted for use, and as the draft-animals continue in motion the belt 28 will be actuated and will thereby transmit motion to the conveyer to conduct the material to the elevator and the elevator to hoist such material, as will be readily understood. When the load has been discharged, the endate of the wa on is replaced, the wagon-bra e released, an( the brake-lever 44 retracted, whereby the tread-belt 28 will be held from movement and will form a stationary platform across which the draft-animals may pass and draw the wagon, which will pass off down the platform 23.

It will thus be seen that my invention provides an apparatus whereby the power of the draft-animals employed to draw the transporting-vehicles may be utilized to elevate the grain or other material carried thereby and that this operation may be performed in a simple and convenient manner without the necessity of employing auxiliary power.

Havin thus described the invention, what is claime as new is* 1. In an elevating apparatus, the combination of a treadmill having inclined approaching and descending platforms leadin thereto and extending therefrom, said mil comprising an endless belt having a drivingshaft provided with a sprocket-gear, an elevator disposed in rear and at one side of the inclined approach and provided with a driveshaft carrying a pinion and a beveled gear, an intermediate power-shaft provided with a beveled gear meshing with the beveled ear on the elevator-shaft and carryingasproc etwheel, a sprocketchain connecting said sprocket-wheel with the sprocket-gear on the treadmill-shaft, a conve Yer-frame pivotally mounted to swing upon the elevator in a vertical plane and adapted to be lowered across the lower end of the inclined approach, said conveyer-frame having a drive-shaft and a conveyer actuated thereby, said shaft carrying at one end a s rocket-wheel, a chain connecting said sproc {et-wheel with the sprocketwheel on the elevator-shaft, and a brake for controlling the treadmill.

2. In an elevatin ap aratus, the combination of a treadmil inc ined passages leading to and from the mill, said mill comprising an endless belt mounted upon shafts, one of said shafts being provided at one end with a sprocket-wheel and at its opposite end with a friction brake-wheel, a ivotall -mountedlever for engaging said rake-w eel and provided with means for lookin it in adjusted position, an elevator dispose at the rear and at one side of the inclined a proach and having a drive-shaft rovided) with a beveled pinion and a sproc et-Wheel, a power-shaft aving a beveled gear 'meshing with said Ipmion, and a sprocket-wheel, a sprocket-c am IIO connecting said s rocket-wheel with the sprocket-Wheel on t e treadmill-shaft, breekets on the elevator-frame, a conveyer havin a drive-shaft journaled in said brackets an pivotaily eonneeting the conveyer thereto, whereby Seid conveyer is adapted to be elevated and lowered to extend across the bottom of the inclined approach, means for securing the oonveyer 1n raised position, a
